Cryer has a storied history with the Luthor family - he played Lenny, Lex's nephew, in the 1987 film Superman IV: The Quest for Peace alongside Gene Hackman, but now he gets a swing at the iconic role himself.

But after being namedropped for years on Supergirl, how will Lex finally enter the Arrowverse? Unsurprisingly, it's a family matter. According to The CW, Lex will make his first appearance in episode 415, "O Brother, Where Art Thou?" when he reaches out from prison to enlist his sister Lena (Katie McGrath) into one of his plans "and will stop at nothing to get her on board, even if that means leveraging the life of one of her friends."
